Introduction (continued)
Heat dissipation
To prevent this product from overheating, heed the
following. Failure to observe this may cause fire or trouble.
• Do not block the cooling fan outlet or the ventilation holes
with a wall, rack, cloth, etc. Maintain the product
periodically to prevent dust from blocking ventilation
holes.
• The lifetime of the cooling fan is limited by use. It is
recommended to replace them after around 30000
hours of operation. Contact your dealer for replacement
of the cooling fans.
• When the internal temperature rises, the fan noise may
become louder.
• Clear a space of more than 5 cm {2 inches} from both
sides, the top, and the rear of the product. Do not block
the ventilation holes on the front side since this product
is designed to cool the hard disk drives by drawing in air
from the front.
Avoid placing this product near noise sources
If the cables are placed near noise sources such as
fluorescent lamps, noises may be produced. In this case,
rewire avoiding the noise sources, or move the product to a
place far from the source.
Grounding
